Adaptation of Obsessive Distrust Inventory to Turkish and investigation of its psychometric properties

Obsessive distrust is conceptualized as an additional domain of relationship and partner-oriented obsessive-compulsive symptoms. The aim of this study was to adapt the Obsessive Distrust In-ventory designed to assess symptoms of obsessive distrust into Turkish and investigate its psychometric properties. The study sample consisted of 420 (227 females and 193 males) participants aged between 18-59 and stated that they were in an ongoing romantic relationship. Partici-pants were asked to fill the scale set containing the Obsessive Distrust Inventory, Obsessive Compulsive Inventory-Revised Form, Obsessive Beliefs Questionnaire-9, Relationship Obsessions and Compulsion Inventory, and Partner-Related Obsessive-Compulsive Symptoms Inven-tory via the internet. According to the results of the confirmatory factor analysis, the factor structure of the Obsessive Distrust Inventory was found to be compatible with the one-factor structure of the original scale. Other analyzes showed that the scale had a satisfactory level of convergent and discriminant validity. At the same time, the internal consistency coefficient, the split-half test correlations, and the Spearman-Brown coefficient showed that the scale had reliability values consistent with those of the original scale. This study demonstrated that the Obsessive Distrust Inventory meets the requirements of a valid and reliable measurement instrument and is suitable for use in the Turkish sample, allowing for cross-cultural comparison.
